The ball mill Ball milling is a mechanical technique widely used to grind powders into fine particles and blend materials. 18 Being an environmentally-friendly, cost-effective technique, it has found wide application in industry all over the world.

2019-2-24 large particle size down to a particle size of 100 m. It is expressed in terms of q, the reduction ratio where q = L 1 /L 2. Note that all of these equations [eqns. (11.2), (11.3), and (11.4)] are dimensional equations and so if quoted values are to be used for the various constants, the dimensions must be

Clarification: Determination of energy required in size reduction is generally done using Kick’s law or Rittinger’s law. The Rittinger’s law is stated as the energy required for reduction in particle size of a solid is directly proportional to the increase in surface area. The kick’s law is defined as the amount of energy required to
